# On MacOSX, using our zlib from TL results in a .a that is unusable; ld
# warns "file is not of required architecture", and does not read it.
# There is no apparent reason for this.  Using --without-zlib evidently
# causes freetype2 to use its internal zlib, so no functionality should
# be lost, even though it is not the cleanest solution.
